Using the Polar Patterns

Perhaps the most important aspect of using your CV3, or any other microphone, is to understand its available polar 
pick up patterns  Every microphone has a characteristic polar pattern that determines how well it accepts or rejects 
signal coming from various areas around the microphone capsule  You can use the CV3’s polar pattern switch, located 
on the PS4 power supply’s front panel, to select one of the available polar patterns  The CV3 provides nine polar pick-up 
patterns; omnidirectional, cardioid, figure-eight, plus transitional patterns in between each of those  This gives you a 
tremendous amount of versatility and sound possibilities  To understand the basics of patterns you need to know the 
three most common patterns; omniderctional, bi-directional or figure-eight and cardioid  The omnidirectional pattern 
produces a linear response regardless of where the sound source originates (in front of the mic, behind it, to the side, 
etc )  If the talent needs to move around and has trouble staying in the same place in front of the mic, using the omni 
pattern can be extremely useful since the off axis change will have less of an effect on the frequency response   When the 
CV3 is set to the figure-eight pattern the microphone picks up sound directly from the front and back while rejecting the 
sound at the sides  When miking an acoustic guitar, a great way to capture some natural ambience is to set the mic in 
figure 8 and position it between a guitar and a reflective surface  
While Omni and Bi-directional microphones are very useful for a variety of applications, many miking situations in 
recording and live sound applications require uni-directional or cardioid microphones  When set to Cardioid, the CV3 will 
accept the sound coming from directly in front, and to reject sound coming from behind or from the sides  The cardioid 
pick-up pattern allows for better separation of instruments in the studio and more control over feedback in live sound 
reinforcement  When positioned correctly, the cardioid pattern allows you to pick up more of the sound you want and 
less of the sound you don’t want  In live sound situations, the polar pattern also determines how prone a particular
